POIRING I Thomas M. APunchak, Clevelandgfh'i Application March 31, 1947; Sria'lf-o.

The invention. aimsto `provide `a novel convenient, advantageous` andidurablepouring cap for connection with a milk bottlefor other container;

toseal thecontaineragainst entrance ofl .air 'after initial opening, andato. permiteasy' and controlled pouring of liquidfrom. thecontainerlwhen desired.

In carryingout the. above end', afifurther obj ect isv to provide "a.novel.constructionawhich 'mayifbe quickly and easily disassembledli for thorough cleaning.

A lstill `furtherobiect. is. .to provide a compara; tively simple device which may be expeditiously manufactured and profitably sold at a reasonable price.

Figure 1 of the accompanying drawings is a vertical sectional view, partly in elevation, cut substantially on line I-I of Fig. 2, illustrating one form of the invention.

Fig. 2 is a vertical sectional view on line 2 2 of Fig. 1.

Fig. 3 is a lower end view of the device shown in Figs. 1 and 2.

Preferences have been disclosed in the drawings and will be rather specifically described, but attention is invited to the possibility of making variations within the scope of the invention as claimed.

In the form of construction shown in Figs. 1, 2 and 3, the numeral 'I denotes a preferably cylindrical body formed from comparatively hard rubber or any other preferred material, such as a modern plastic. This body, in the present disclosure, is formed with a socket 8 which opens through the lower end of said body, and the upper portion 9 of said socket is o reduced slotlike form. This socket portion 9 communicates with the interior of a tube I which is unitarily connected with the body l and virtually forms a part thereof. The tube Ill is secured in a groove I I in the major portion of the body and is formed with a slot I2 registering with the upper portion 9 of the socket 8. Either end of the tube I0 may constitute a liquid outlet for discharging the liquid from a container with which the device is connected, and the other end of said tube will then constitute an air inlet for admitting air to the container during the discharge of liquid. It will thus be seen that if the air-admitting end of the tube be closed with the thumb or one linger, the

discharge of liquid will be stopped, providing for easy control of liquid discharge.

Around the open lower end of the socket 8, the body 'I is formed with an annular downwardly facing surface I3, and at the outer edge of said cylindricalidowmvrdlyrproiectingiaange? Ik. In

Jche hangen sintende-@iter iron-n1 A.fg-ripari@ VAurowrril ardlyfienrm @insert lfccupies-thei majonp`ortizarrierth socktiE-fandini-tlreipresentdisclosure comprises atop disk I1 and a cylindrical side wall I8 unitarily connected with said top disk. The lower end I9 of the side wall I3 projects downwardly below the annular surface I3 to provide a second downwardly projecting cylindrical ange at the inner edge of said surface I3. This ilange is intended for reception within the upper end of a milk bottle neck and is shaped to t tightly upon the usual cap seat 20 as shown in Fig. 1.

The disk I'I is formed with a diametrically eX- tending slot 2I and with openings 22 at the ends of said slot, said openings and slot extending from the upper to the lower side of said disk. A gravity-seated valve 23 is normally so positioned as to close the slot 2I and openings 22 as seen in Fig. l, but when the bottle and the attachment are properly tilted, said valve 23 will unseat. Then, air enters the container through one end of the tube I0, one of the openings 22 and the space surrounded by the side wall I8, and liquid from the container discharges through this space, the other of the openings 22, and the other end of the tube IIJ. The valve 23 comprises an elongated head 24 in the socket portion 9 which constitutes the valve chamber, and a downwardly projecting stem 25 integral with said head 24, said stern being slidably and non-rotatably received in the slot 2|. If desired, this stem may have an opening 26 but this is not essential. The ilat-sided stem 25 and the slot 2l coact in preventing turning of the valve 23 with respect to the insert I 6, and this insert is held against turning within the body l, by means of a vertical rib or key 2l' secured to the wall I8 and slidable in a groove 28 in the body. The entire insert I6 is preferably held in place by friction and may thus be readily removed to permit removal of the valve 23 and access to all parts for thorough cleaning.

From the foregoing taken in connection with the accompanying drawings, it will be seen that novel and advantageous provision has been dis- Surface I3, said body is formed With an integral closed for carrying out the desired ends, and while i' intendedpreferences have been illustrated, attention is again invited to the possibility of making variations within the scope of the invention as claimed. All parts are preferably formed from comparatively hard rubber or other suitable plastic, but any suitable material or materials may be used.

I claim:

1. A pouring cap for milk bottles having an internal closure supporting shoulder, said cap comprising a body having a closed upper end and a recess extending upwardly from its lower end, said recess having a lower portion of a diameter to fit tightly on the mouth of a milk bottle, a median portion of substantially the same diameter as the outer diameter of the said closure supporting shoulder, said recess further having an upper valve receiving portion of less area than the median portion, a transverse tube communicating with the last mentioned Portion of the recess and having one end constituting an air inlet and the otherendconstituting a'uid outlet, a valve seat slidably supported in the median portion of the recess and a gravity activated valve porting shoulder, said recess further having an upper valve receiving portion of less area than the median portion, a transverse tube communicating with the last mentioned portion of the recess and having one end constituting an air inlet and the other end constituting a uid outlet, a valve seat slidably supported in the median portion of the recess and a gravity activated valve in said valve receiving portion of the recess, said tube being longitudinally slotted on its under side to communicate with the valve receiving portion of the recess, said valve being of elongated form and shaped to open into the slot in said tube and seat on said valve seat, and means to hold said elongated valve in alinement with said tube.
